Hey guys, I recently upgraded my computer. Here are the parts: AsRock 970 Extreme4 AMD Phenom II 1055T Patriot G2 8GB kit (I don't think this is the problem) Also I have a Noctua U9B SE2 heatsink. First I tried to overclock the CPU manually, by raising the bus speed to 243MHz (for 3.4GHz), stress tested it, and it crashed. Then, I raised the CPU voltage to 1.4000, which I figured was high enough (?). I tried it again, and it crashed. By now I figured maybe I wasn't doing it right, so I used the motherboard's own 'optimised' overclock settings, and set it to 3.2GHz. This crashed again! Then, when I tried to boot it (before this it booted fine), it would load into Windows and show a black screen and a mouse (the mouse worked if that means anything). Am I doing something wrong? The CPU's Turbo Core is supposed to let it run to 3.3GHz. This has been quite disappointing to say the least, especially after seeing others get overclocks of 4GHz+ with the same CPU.
